Teach you to pull out the garbage proxy IP handily
Brothers engaged in network projects understand that the proxy IP is like a delivery boy, slow delivery and always lost certainly can not be. Today, we will teach the guys a few earth methods, with their own tools can be measured which proxy IP is a pitiful goods.
Tips for measuring speed
First, save the list of IPs to be measured into a txt file, which is recommended.ipipgo online detection toolThe fact that you don't have to install software is really nice. Focus on three indicators:
Response time 20% -- directly pull black
Geographic location deviation -- don't believe what the advertisement says.
To cite a chestnut, the last time I measured an IP claimed to be in Shanghai, the results connected to the Yunnan server room, this kind of goods before it is too late to throw away.
Anonymity and other levels are ignored
Many agents will brag about high anonymity, we can only rely on our own verification. Use this command to check the request header:
curl -I --proxy http://IP:端口 http://checkip.ipipgo.com
Look at the return header forX-Forwarded-ForThe unique technology of ipipgo wipes out such marks and has been tested and proven to be reliable.
There's something to be said for survival time.
Temporary IP and long-lasting IP are suitable for different scenarios:
| typology | Scenario | Recommended Programs |
|---|---|---|
| short-lived IP | ticket scalping in seconds | ipipgo dynamic pool |
| persistent IP | Data Crawling | Exclusive access to ipipgo |
Last week to help a friend debugging crawler, with ordinary IP blocked for three days, replaced with ipipgo's enterprise-class long-lasting IP stable as the old dog.
Avoiding the Pit Q&A
Q: What should I do if the detection tool shows that it is available, but it always times out when I am actually using it?
A: 80% encounteredServer room fire protectionI've changed to ipipgo's hybrid protocol node, which supports dual channel switching between socks5 and http.
Q: What if I need to detect a large number of IPs at the same time?
A: The ipipgo developer backend has theBatch job inspection interfaceRemember to set a 2-second timeout threshold and don't wait for spam IPs!
Q: Detecting that the IP works but the actual service fails?
A: It may have triggeredDeep Protocol RecognitionIt is recommended to enable the protocol masquerade mode in the ipipgo console.
Private Debugging Tips
Finally, I'll share a trick: usingMulti-node relay detectionThis is the first time that a US node requests a Japanese server. For example, first let the U.S. nodes request Japanese servers, and then use the Japanese nodes to connect back to the domestic, this kind of nesting test can expose the 90% problem IP. ipipgo's global relay network is specially optimized for this kind of scenario, the latency can be pressed to within 300ms.
Remember, a good proxy IP is like finding a date, it's useless to just look at the ads, you have to personally inspect the goods. If you're too lazy to use ipipgo, you can use it directly.Screened IP library, their home quality control report is more detailed than my baby's report card, with all indicators clearly labeled.
